Hi there!

I’m newby in “Zynthian” but…

My zynthian project is almost done…  
I used the “prototype-1” scheme with a PI4 (source: [A Build with Variations](https://discourse.zynthian.org/t/a-build-with-variations/324)), a screen, four encoders and an USB Audio… It’s my “speciality” becouse, I just I sacrificed my old ALESIS io2 Express USB sound card, and my EDIROL PCR-800 MIDI master keyboard…

I dissasambled the io2, and built in into the PRC-800 with the zynthian…

The result a bit ugly yet now 😛 but it’s will be nicer of course.

The most important thing is my zynthian setup is alive! 🙂

Raspberry PI4B / 4G RAM  
Waveshare 4.3 inch DSI LCD  
PROTOTYPE-1 wiring  
ALESIS io2 sound card with

- USB MIDI IN/OUT
- DIN MIDI IN/OUT
- 2x balanced AUDIO IN MIC/LINE/GUITAR with +48V phantom
- 2x AUDIO insert IN (for external FX)
- 2x AUDIO OUT (44100 Hz/24bit with 5ms latency)
